Description

Removed the unused PythiaArchitectureAdapter.

As discussed in #1302, the adapter was not wired into ArchitectureAdapterFactory, so Pythia models were already being handled through NeoxArchitectureAdapter via the GPTNeoXForCausalLM path.

Changes made:

• Removed transformer_lens/model_bridge/supported_architectures/pythia.py
• Removed PythiaArchitectureAdapter from transformer_lens/model_bridge/supported_architectures/__init__.py

Relevant to issue #1302
